Pressure Reducing & Solenoid Shut-Off Valve

Product Advantages

  • Accurate Pressure Control
  • Wide Adjustment Ranges
  • Optional Check Feature Available
  • Quick Acting Solenoid Shut-Off
  • Easy Installation and Maintenance

The Cla-Val Model 93-01 Combination Pressure Reducing and Solenoid Shut-Off Valve consists of a Cla-Val Hytrol main valve, a reducing control and a solenoid control connected to the main valve. This valve automatically reduces higher inlet pressure to a steady lower downstream pressure, regardless of changing flow rate and/or varying inlet pressure.

The 93-01 is an accurate, pilot-operated regulator capable of holding downstream pressure to a pre-determined delivery pressure. When downstream pressure exceeds the pressure setting of the control pilot, the pilot valve and main valve close drip-tight. A solenoid control is provided to intercept the operation of the pressure reducing control and close the main valve. This valve is furnished either normally open (deenergized to open), or normally closed (energized to open). Pressure setting adjustment is made with a single adjusting screw.

Typical Applications

Electronic Control Service
A typical application for this valve is to reduce high transmission line pressures to lower distribution system levels, while opening and closing on command. The solenoid control feature can be activated by an electrical signal from a timer or programmer.

Fire Service
The Model 93-01 can be installed in a distribution line where there is a need to close the valve on the starting of a fire pump. The solenoid control is activated on pump start-up and closes the valve.
